Deterioration and detailing deficiencies present an ongoing challenge when assessing existing reinforced concrete structures. To investigate this problem further, CIRG member Michele recently performed a study which looked to understand bond in the context of differing confinement conditions such as cover depth and the presence of transverse reinforcement. The study found that splitting cracks impacted the contribution of the transverse reinforcement and that maximum bond strengths were obtained for intermediate cover to transverse reinforcement diameter ratios. CIRG members continue to provide insights on making concrete more sustainable, and these findings can assist in implementing effective assessment and maintenance strategies in existing concrete assets. Please read about our work on our website and reach out to our members to discuss their research.
